COMBINED FORM TIE AND WALER SUPPORT Chester I. Williams, Grand Rapids,Mich.

Application November 19, 1948, Serial No. 61,030

9 Claims. (Cl. 25-131) This invention relates to a combined form tie andwaler support for use with concrete forms in which concrete is poured toform foundations, walls and the like. Concrete forms are ordinarilycomposed of sheathing, nailed or otherwise secured to studs inconnection with walers which are held tightly against the studs. Inpouring each wall section two spaced formsare used, each one defining aface of the wall or the like, and tie rods are provided between the twoforms. Ordinarily cleets or other supports are secured to the studs forsupporting the walers, and ordinarily the tie rods extend to the outerfaces of the walers and are provided with nuts or the like fortightening up the tie rods. Forms for an entire wall may be erected asusual.

One of the objects of the present invention is to provide a combinedform tie and waler support by which the forms are properly spaced apart,and the walers held against the studs of the forms.

Another object is to lessen the cost of manufacture of devices of thischaracter, and to provide a device which may be readily secured in placeand removed therefrom.

With these and other objects and advantages in view, this inventionconsists in the several novel features hereinafter fully set forth andmore particularly defined in the appended claims.

The invention is clearly illustrated in the drawings accompanying thisspecification in which:

Fig. 1 is a horizontal view, partly in section, through a concrete formand showing in plan a combined form tie and waler support embodying thepreferred form of the invention.

Fig. 10 is a view partly in side elevation, and partly in vertical crosssection of the parts seen in Fig. 9.

Fig. 11 is a perspective view of a clamp plate forming part of themodified form shown in Figs. 9 to 12. And

Fig. 12 is a respective view of a certain hanger bar associated with theform of the invention illustrated in Figs. 9 to 12 inclusive.

Referring to said drawings and first to Figs. 1 to 4 inclusive, thereference character 5 designates a section of a concrete form ordinarilycomposed of a plurality of studs one of which is seen at 6 to whichsheathing 7 is secured by nails or the like as is customary. Two suchforms are used in pouring a section of a wall or the like, one of eachside with the sheathing of each form facing the other. A waler is seenat 8 and may comprise two 2 x 4s, 3a or other timbers, or the walers mayeach comprise a single piece of timber. The tie rod element of thedevice is seen at 9 and extends through holes in the sheathing of bothforms and together with the waler supports, connect and space apart thetwo forms. The waler supporting element of the device is seen at 10 andone is fastened to the tie rod at each end thereof. The fastening meansbetween the tie rod and waler supports may take several forms, but theone illustrated in Figs. 1 to 4 is simple and comparatively inexpensive,and is produced by punch press operation. As shown, several tongues 11,1-2 are struck up from the body portion 13 of the waler support and arebent to stand at right angle to the body portion. The tongue 11 isformed with a hole 13a therethrough, and the tongues 12 may be T-shapedas shown. The construction of the tongues 11 and 12 provide means forpreventing transverse movement of the tie rod and axial movement of thetie rod. I

Each end of the tie rod is warped, offset or undulating as at 15, andeach offset, warped or undulating end of each tie rod is insertedthrough the hole in the tongue 11 and wrapped about the shanks 16'of thetongues 12. Practice has shown that this form of connection between thevtie rod and waler supports is very effective, and serves to space theforms apart. The waler supports may be temporarily secured to the studsas by nails 17 or the like which are driven through nail holes 18 in thewaler support and into the stud. With the waler supports secured to thestuds and connected by a tie rod the forms are properly spaced apart andcannot separate from each other. spaced relation.

The waler supports are constructed and arranged to hold the walertightly against the studs and various forms of connections between thewaler and waler supports may be had. As shown in Figs. 1 to 4 the walersupport has a loop which surrounds the waler and as shown is formed withtwo parallel arms 20, 20a that project from one end of the body portionand said arms are spaced apart to receive a waler between them. The arms20, 20a are of a length to extend somewhat beyond the outer side of thewaler, and in use these outer ends of the arms are connected by one ormore cross bars 21, 21a here shown as comprising angle shaped bars, onedisposed at each side of the arms 20, 20a. The cross bars 21, 21a areconnected to the arms 20, 20a by suitable means, and as here shown arepivotally connected at one end to the arm 20a as by a rivet 22 or thelike which extends through both bars 21, 21a and the arm 20a. The otherarm 20 is formed with means whereby the bars may be forced tightlyagainst the waler. This arm as shown is formed with a lateral projection23 such as a hook which may be engaged by a claw of a claw hammer, andby it the bars may be pressed back tightly against the outer face of thewaler. Holes 24, 25 are formed in the cross bars 21, 21a and arm 20respectively which are brought into register when the cross bars havebeen swung back tightly against the waler, and a nail 26 or the likesuch as a cotter pin is driven through the holes 24, 25 to connect thecrossbars to the arm.

The tie rod may be flattened as at 27', at places adjacent the forms,whereby to weaken the tie rod at these places. This provides breakingpoints whereby the offset, warped or undulating ends of the tie rod maybe broken off after the forms have been taken down.

In the modified form of the invention illustrated in Figs. 5 to 8inclusive, the tie rod 9 is secured to the waler supporting elements 10ahaving a body portion 13a as in the preferred form shown in the Figs. 1to 4, and a latch 28 pivoted to the waler supporting element as by arivet 29 may be employed to positively lock the Warped end of the tierod to the waler supporting element. The pivoted latch 28 provides meansfor preventing transverse movement of the tie rod. Outwardly extendingtongues 12' formed from the body portion 13a, provide means forpreventing axial movement of the tie rod.

The waler supporting element is formed with an extended portion 20 whichextends between two timbers 81:, that compose the waler. On the end ofthe extended portion 20 is a clamping member 21 which is secured to theextended portion 20 as by a rivet or the like 26a which extends throughthe clamping member 21 and the extended portion 20 of the walersupporting element. A waler hanger bar 31 is fastened to the stud 6 asby a nail or the like 32. Both the hanger 31 and the clamping member 21may be formed with inturned ledges The tie rod and waler supports tiethe forms in 33 upon which the lower timber 8a may rest. The uppertimber 8a rests upon the top of the extended portion To hold thesheathing 7 against the stud 6, a stud lock or washer 34 may be employedon the tie-rod.

In the modified form ofthe invention illustrated,.in Figs. 9 to 12inclusive, the rod 9a is threadedly secured in a she-bolt 35 whichextends throuugh the sheathing 7 along side the stud 6 and extendsbetween the two timbers 8a which serve as a waler. On the outer end ofthe she-bolt is a clamping plate 36 which is pressed against the walerby a nut 37 on the end of the she-bolt 35. A waler hanger 38 is nailedto the stud as at 39 and is secured to the she-bolt as by staking orknurling the latter as at 40 on both sides of the hanger bar 38. Boththe bar 38 and the clamp plate 36 are formed with inturned flanges 41which support the waler until the clamp plate is drawn tightly againstit as by screwing up thenut 37.

To hold the sheathing 7 against the stud '6, stud lock or washer 34a maybe secured upon the she-bolt so as to bear against the sheathing.

In either modified form the lower end of the clamping member is swungoutward to permit the lower timber 8a to be inserted between theclamping plate and stud, after which the clamping plate is swung intoupright position permitting the upper timber to be placed between theclamping plate and stud.

It is understood that the parts described are duplicated on the oppositeside of the concrete wall to be poured. Therefore, it is believed that adescription of one will sufiice for both.

Having thus described my invention, it is obvious that variousimmaterial modifications may be made in the same without departing fromthe spirit of my invention; hence, Ido not wish to be understood aslimiting myself to the exact form, construction, arrangement andcombination of parts herein shown and described or uses mentioned.
